Module: reefvision.widgets.window

Source: ./reefvision/widgets/window.reef

Overview

reefvision.widgets.window — framed Group (design §5 / object-rewrite §5)

object Window extends view.Group. Outer bounds include the frame. Children use client-relative coords (0,0 = top-left inside the frame). Client inset is 1 cell on each side; the title bar reuses the top frame row.

Chrome: drag title to move; bottom-right grip to resize (min + clamp). Optional system controls are ONE title-cap block (order left→right): ┤ _ + x ├ (maximized shows = instead of +; close is lowercase x) _ minimize → CMD_MINIMIZE

maximize → CMD_MAXIMIZE (toggle restore) x close → CMD_CLOSE Glyphs always use the title style (never a focused/highlight style). Esc emits event_command(CMD_CLOSE) when the client does not consume the key.

Usage: let win = new window.Window(cell.rect(4, 2, 40, 12), "Tools") win.set_closable(true) win.add(new button.Button(cell.rect(2, 2, 10, 1), "OK", event.CMD_OK()))

Keep the window reachable after a terminal resize:

size is capped to the content area (not below min when possible)
origin is shifted so the title row intersects the area
if still impossible (tiny area), pin to area top-left
